Protocol 3.0 §5 (docs/link/v3.md). The shard publishes its own ruleset —
expansion, which optional systems are on, skill/stat caps, account and house
limits, champion scroll rules, the save/restart schedule — and the site renders
it, so the rules page cannot drift from how the shard actually plays.
Server
- shard_ruleset: a singleton table (id = 1) holding the whole frame in
`payload`, with `rev` and `expansion` hoisted. Nothing is normalized out:
the frame is a flat description of config read as one page, and splitting it
into columns would mean a schema change every time the shard grows a block.
- shardIngest routes world.ruleset to setRuleset and deliberately does NOT
log it — the shard re-emits the whole ruleset on every sidecar connect, so
logging would append a duplicate row per reconnect, and server.hello already
marks each of those.
- uoLinkSocket backfills GET /ruleset explicitly rather than via snapshot(),
which asserts an array; this covers the order where the sidecar was already
up and holding the ruleset when we reconnected.
- GET /public/shard/ruleset behind requireFeature('ruleset') and projected,
per §3.6.1's rule that a shard read which doesn't project is a bug. `null`
means the shard has never published one — a real answer, distinct from a
published ruleset, and the page says so.
Client
- routes/public/Rules.jsx at /site/rules, live via world.ruleset (a frame is a
complete ruleset, not a delta, so the newest one wins outright). Caps are
rendered from tenths — 7000 is 700.0, and showing the raw number would
mislead. A systems key this build doesn't know still renders, humanised, so
a newer plugin can't go invisible against an older client.
- Nav entry gated on the `ruleset` feature, so it hides rather than 403s.
Verified end to end against the local MariaDB and a sidecar fed by a fake shard:
backfill snapshot, live SSE delivery of a changed ruleset, REST reflecting the
overwrite, an empty /feed (not logged), and the gate — 200 by default, 403 at
audience=staff (and dropped from /features so nav hides it), 404 when disabled.
Page rendered clean at all breakpoints checked, no console errors.
497 server tests pass; routes.manifest.json, routes.guards.json and the OpenAPI
spec regenerated.
